What Allen said, plus:
The first 16B tombstone, which is what 37silverstreak has, retained the 1933 five-band chassis but added a 10-1/2 inch H series speaker. This chassis has the single shaft tuning control which is pulled out for slow speed tuning and pushed in for faster tuning. So a single large hex knob with a set screw must be used.
This is the earliest 16B tombstone model of the 1935 season, which came out in the summer of 1934. By Fall, Philco had switched to their new four band chassis which requires the concentric tuning knobs.
